At suitable distances above the grate capped openings S are provided inthe walls of the gas producer through which the fire may be observed andthe material may be agitated by pokers.

What we claim to be new is 1. In combination with the wall of a gasproducer, a casting fastened to said wall and provided with a centralopening, the marginal edge of which is provided with an annular groove,a series of grate bars, the upper ends of which are angled and rest uponthe projecting bottom wall of said groove, a ring, links pivotallyconnecting the same to said casting and upon which the lower ends ofsaid grate bars rest, said ring having an annular shoulder upon theinner periphery thereof, and a grate resting upon said shoulder of thering, as set forth.

2. In combination with the wall of a gas producer, a casting fastened tosaid wall and provided with a central opening, the marginal edge ofwhich is provided with an annular groove, a series of grate bars, theupper ends of which are angled and rest upon the projecting bottom wallof said groove, a ring having shouldered portions upon the innermarginal edge thereof, the lower end of said grate bars resting upon oneof said shoulders, links pivoted at their upper end in grooves formedupon the under surface of said casting, their lower ends pivoted to saidring above the lower ends of the grate bars, a grate mounted upon saidring and resting upon the lower of said shoulders, as set forth.

In testimony whereof we hereunto affix our signatures in the presence oftwo witnesses.
